Avalanche Activity

Thoroughly wet snowpack and wet-snow avalanches due to rainfall

Due to rain impact, increasingly frequent naturally triggered wet slides and avalanches are possible in zones which have not yet discharged. On steep grassy slopes, glide-snow avalanches still threaten.

Snowpack Structure

The shallow old snowpack is being weakened by rainfall and lack of nocturnal outgoing radiation, it softens up further during the daytime. All in all, there is not much snow on the ground. Avalanche Warning Services no longer have as much information from these regions.

Weather Synopsis

Nocturnal hours: in the early part of the night, intensive showers from the north, some thunderstorms. Later it will taper off, clouds disperse somewhat. Saturday: mixed conditions, including brief rain showers, snowfall above 2400 m. At 2000 m: 1-6 degrees. Moderate to brisk westerly winds.

Tendency

Intermittent sunshine, a bit of convective cloud build-up, pleasant conditions, showers possible in the southern regions, snowfall above 2400 m. Due to lack of outgoing nocturnal radiation the snowpack cannot freeze, making wet-snow avalanches to be expected.
